A Jailbroken executable which could dump the iCloud account token saved in the iDevices. What is Token ?? If you get it, you wont need to know the credentials or the password to access the iCloud account. You can use it on any other reverse-engineering or educational purposes. (e.g. Elcomsoft Password Breaker's Download from iCloud Account feature).
It would give you two kind of information stored in keychain. They are iCloud Account ID and a token which was automatically generated while signing into the iCloud API.
For example,
8325186261:AQAAAABWIlwNcjGZBat9sSMxDnkk1nBCnjJGwZM=
The first number on that line represented the account id and the second one is token. But remember always, that token can be expired.
You would need a mac based machine to compile this.
Based and enhanced on Keychain-Dumper.
Open up the Keychain Access app located in /Applications/Utilties/Keychain Access
From the application menu open Keychain Access -> Certificate Assistant -> Create a Certificate
Enter a name for the certificate, and make note of it, as you will need it later when you sign iAex. Make sure the Identity Type is “Self Signed Root” and the Certificate Type is “Code Signing”. You don’t need to check the “Let me override defaults” unless you want to change other properties on the certificate (name, email, etc).
You should be able to compile the project using the included makefile.
make iAex
If all goes well you should have a binary iAex placed in the same directory as all of the other project files.
First we need to find the certificate to use for signing.
make list
Find the 40 character hex string corresponding to the certificate you generated above. You can then sign iAex.
CER=<40 character hex string for certificate> make codesign
You should now be able to follow the directions specified in the Usage section above. If you don't want to use the wildcard entitlment file that is provided, you can also sign specific entitlements into the binary.
The resulting file can be used in place of the included entitlements.xml file.
If you find a bug you can open an issue.
